What is Inmarsat C?
Inmarsat C is a digital satellite communication system whereby anything that can be encoded into digital format, whether text, numeric data from instruments or other information in digital form, can be sent and received over the system. The Inmarsat C system is known as store-and-forward messaging system. When sending a ship-to-shore message, it is edited on the terminal and then transmitted in a series of data packets to an Inmarsat C land earth station (LES). The LES acts as an interface (or gateway) between the satellite and the terrestrial telecommunications network. If the LES receives any data packet in error, it signals back to the terminal to re-transmit those packets and the procedure repeats until the LES has received the complete message with no errors. The LES stores the data packets, assemblies them into a single message and forwards it (hence the term store-and-forwarding) over the telecommunication network to its addressed destination.
